<u>ANSWER:</u>

Sedimentary rocks make up the least part of the earth's crust.

<u>EXPLANATION:</u>

  • The sedimentary rocks form a 'thin layer of the earth's crust' and form just about 5% of the crust.
  • The metamorphic and igneous rocks cover about '95% of the earth's crust'.
  • The sedimentary rocks are found near the 'surface of the earth' because these are formed by the processes that occur on the surface.
  • The 'igneous and metamorphic rocks' are found in the 'earth's crust' because these are formed by processes that take place deep inside the earth.

Continued movement of the continental crust on the west side of the San Andreas fault could result in which of the following fea
Mamont248 [21]

Answer:

Option (C)

Explanation:

San Andreas is a prominent example of a transform fault, in which the plates namely the Pacific Plate and the North American plate slide past each other. The movement of the associated plates in this fault is in the right lateral, strike-slip. With the continuous and rapid movement of both the plates in its respective direction, the west side of the fault would get detached from the fault zone and lead to the formation of an island. The movement of the plates along this fault is responsible for the occurrence of shallow focus tremendous earthquakes.

Thus, the correct answer is option (C).

Why do tropical communities tend to have greater species diversity than temperate or polar communities?
kozerog [31]

Answer:

Tropical climates are better suited for a multitude of species of plants and animals.

Explanation:

The reason for this is tropical climates are easier to handle then harsh winters because almost all tropical climates are near the equator so it tends to stay warmer year round creating a year round growing period. Polar climates are harsher on the plants than the animals. Also consider this the fact that there would be no herbivore animals for predators to eat so that limits what can grow in the polar climates.
